Topaz 2: Electric Blue-galoo
There is no topaz one. I just needed to make that joke.
This is my most recent finished stone: a 4.65ct, 10.3mm electric blue topaz in a modified standard round brilliant. The modification is a slightly shallower pavilion and a much shallower crown to enhance brightness at the cost of some weight, but I'm not too concerned about size. It's all about making the stones look nice, and I think I did a decent job on this one.
Learned a lot about adjusting speed and wheel rotation direction to combat smaller issues, and there was a lot of trial and error on polish, settling on 100k to clean it up. Topaz is interesting to work with, but not my favorite. Oh, and NFS, because rules, haha.
